The Sumatran rhinoceros or Dicerorhinus is the smallest rhinoceros, it stands 3.67–4.76 ft. high at the shoulder, with a head-and-body length of 7.7 to 10.4 ft. and a tail of 14 to 28 in.
The Sumatran rhinoceros or Dicerorhinus are now critically endangered, with only five substantial populations in the wild: four in Sumatra and one in Borneo.
There has been little opportunity to study epidemiology in the Sumatran rhinoceros. Ticks and gyrostigma were reported to cause deaths in captive animals in the 19th century.
The rhino is also known to be vulnerable to the blood disease surra, which can be spread by horse-flies carrying parasitic trypanosomes; in 2004, all five rhinos at the Sumatran Rhinoceros Conservation Center died over an 18-day period after becoming infected by the disease.
The Dicerorhinus or Sumatran rhino has no known predators other than humans. Tigers and wild dogs may be capable of killing a calf, but calves stay close to their mothers, and the frequency of such killings is unknown.
Although the rhino’s range overlaps with elephants and tapirs, the species do not appear to compete for food or habitat. Asian elephants (Elephas maximus) and Sumatran rhinos are even known to share trails, and many smaller species such as deer, boars, and wild dogs will use the trails the rhinos and elephants create.
The Dicerorhinus or Sumatran rhino maintains trails across its range. These trails fall into two types. Main trails will be used by generations of rhinos to travel between important areas in the rhino’s range, such as between salt licks, or in corridors through inhospitable terrain that separates ranges.
In feeding areas, the rhinos will make smaller trails, still covered by vegetation, to areas containing food the rhino eats. Sumatran rhino trails have been found that cross rivers deeper than 4.9 ft. and about 160 ft. across. The currents of these rivers are known to be strong, but the rhino is a strong swimmer.
A relative absence of wallows near rivers in the range of the Sumatran rhinoceros indicates they may occasionally bathe in rivers in lieu of wallowing.
